| 1 | 吸烟,血清抗氧化维生素水平和老年性黄斑变性之间的关系(英文)显示文摘目的:研究老年性黄斑变性(AMD)等级、血清抗氧化维生素水平(维生素A、C和E)和吸烟的关系。方法:对84例患者行黄斑彩色眼底成像,根据AMD损伤率和损伤程度将其分为五组(等级I^V)。应用高效液相色谱法(HPLC)测量血清抗氧化维生素水平。根据吸烟状况分不吸烟者、已戒烟者和吸烟者三组,并统计吸烟者每年的吸烟总量。结果:对照组中,维生素A、E、C水平分别为0.874±0.326mg/L,10.739±4.874mg/L和1.737±0.447mg/L,AMD组中分别为0.880±0.305mg/L,9.487±6.060mg/L和1.870±2.191mg/L,无显著差异(P>0.05)。AMD不同等级分组间维生素A(P=0.881)和E(P=0.293)水平差异无统计学意义,维生素C水平(P=0.044)随AMD程度的加深而增加。根据吸烟状况,AMD组与对照组之间无显著差异。根据每年的吸烟总量,两组之间有显著差异(P=0.02)。AMD越严重,年吸烟总量越高(P=0.007)。结论:研究结果显示AMD与维生素A、E血清水平无关,但和维生素C的血清水平相关,并与吸烟量有关。 | Sezen Akkaya Cakir Ozlem Sahin Haluk Kazokoglu Feyza Tekeli Goncagul Haklar Yelda Ozkurt | 2014 | 国际眼科杂志2014，14，5： | 5 |
| 2 | Airborne Pollen Grains Of Afyon, Turkey显示文摘The airborne pollen grains of Afyon have been studied for a two_year period (1999-2000) with a Durham sampler. A total of 14 367 pollen grains belonging to 40 taxa have been identified and recorded with some unidentified ones. Of them, 6 732 were identified in 1999 and 7 635 in 2000. Of the total pollen grains, 69.67% were arboreal, 26.64% non_arboreal and 3.68 % unidentified. The majority of the investigated pollen grains were from Pinus, Gramineae, Cupressaceae, Platanus , Chenopodiaceae/Amaranthaceae, Quercus, Ailanthus, Moraceae, Juglans , Salix, Cedrus and Rosaceae. The highest level of pollen grains was in May. | Adem BICAKCI 1, Süheyla ERGUN 2, Sevcan TATLIDIL 1, Hulusi MALYER 1, Sabri ?ZYURT 2, Ahmet AKKAYA 3, Nihat SAPAN 5 Department of Biology, Faculty of Science, University of Uludag, Bursa, Turkey 2.

| 3 | Clinical significance of activity of ALT enzyme in patients with hepatitis C virus显示文摘AIM: To investigate serum alanine aminotransferase (ALT) levels in relation to the clinical,biochemical,ultrasonographic and histological characteristics of patients with hepatitis C virus. METHODS: Duration of disease,HCV-RNA,liver steatosis,and the hepatitis activity index (HAI) were correlated with serum ALT in 36 patients with HCV. ALT values were also investigated in 16 control subjects without any liver diseases. RESULTS: In bivariate analyses,ALT levels correlated with duration of HCV infection (P < 0.01),HCV-RNA (P < 0.05),and the HAI (P < 0.01). Among the components of the HAI,ALT concentrations were significantly associated with periportal bridging/necrosis (P < 0.01) and fibrosis (P < 0.05). In multivariate analysis,periportal bridging/ necrosis (β = 0.508; P < 0.01),duration of HCV infection (β = 0.413; P < 0.01),and HCV-RNA (β = 0.253; P < 0.05) were independently associated with ALT activity. The normal ALT activity for men and women was < 23 IU/L and < 22 IU/L,respectively. CONCLUSION: In patients with HCV,alterations in the liver tissue as reflected by ALT elevation are mainly associated with periportal bridging/necrosis,viral load and duration of disease. A cut-off value < 23 IU/L distinguished with high diagnostic accuracy healthy controls from patients with HCV. | Onder Akkaya Murat Kiyici Yusuf Yilmaz Engin Ulukaya Omer Yerci | 2007 | World Journal of Gastroenterology2007，13，41： | 2 |
| 4 | Subthreshold micropulse laser versus intravitreal anti-VEGF for diabetic macular edema patients with relatively better visual acuity显示文摘AIM:To compare the effects of yellow(577 nm)subthreshold micropulse laser(SML)and intravitreal(IV)anti-vascular endothelial growth factor(VEGF)treatment in patients with diabetic macular edema(DME)with relatively better visual acuity[best corrected visual acuity(BCVA)≤0.15 log MAR].METHODS:The medical records of 76 eyes of 47 patients underwent IV(0.5 mg)anti-VEGF injection or SML for the DME with relatively better BCVA were reviewed.The IV group received three consecutive monthly IV anti-VEGF injections,then were retreated as needed.The laser treatment group was treated at baseline and 3 mo,and then retreated at 6 and 9 mo if needed.All participants were followed up for one year.The mean BCVA and mean central macular thickness(CMT)values changes over the follow-up were evaluated.RESULTS:Twenty-four and 23 patients were assigned to the SML and IV subgroups,respectively.The mean number of treatments was 3.64±0.76 in SML group and 5.85±1.38 in IV group(P<0.05).The subgroups were similar with regard to the mean BCVA score at baseline and at the 1st and 3rd months,but the score of SML group was better than that of IV group at the 6th,9th,and 12th months(P<0.05).The decrease in the mean CMT values from baseline values was higher in SML group at the 6th,9th,and 12th months(P<0.05).CONCLUSION:Yellow SML treatment is superior to IV anti-VEGF injection in DME patients with relatively better BCVA for increasing visual acuity and decreasing CMT at 6,9,and 12 mo.SML can be a good alternative first-line therapy for DME with BCVA≤0.15 log MAR. | Sezen Akkaya Banu Acιkalιn Yusuf Emre Dogan Fatih Coban | 2020 | International Journal of Ophthalmology(English edition)2020，13，10： | 2 |

| 16 | Availability of seismic vulnerability index(K_g) in the assessment of building damage in Van, Eastern Turkey显示文摘The seismic vulnerability index(Kg) is a parameter that depends on the dynamic properties of soil. With this parameter, it is possible to evaluate the vulnerability of a point-based site under strong ground motion. Since it is related to the natural vibration period and amplification factor, the parameter can be calculated for both soil and structure. In this study, HVSR microtremor measurements are recorded at more than 200 points in the Van region to generate a seismic vulnerability index map. After generating the map, it is determined that the hazard potential and seismic vulnerability index is high at the sites close to Van Lake and at the densely populated city center. Damage information of the buildings investigated after the 2011 Van earthquakes(Mw = 7.1) are placed on the seismic vulnerability index map and it is realized that there may be a correlation between the damage and the seismic vulnerability index. There is a high correlation, approximately 80 percent, between the damage rate map based on the damaged building data and the K_g values. In addition, vulnerability indexes of buildings are calculated and the effect of local soil conditions and building properties on the damage levels are determined. From the results of this study and the site observations after the 2011 Van earthquakes, it is found that structural damage is not only structure-dependent but is also related to the dynamic behavior of soil layers and local soil conditions. | ismail Akkaya | 2020 | Earthquake Engineering and Engineering Vibration2020，19，1： | 1 |
